To all whom it may concern.-

Be it known that we, WILLIAM BEHAN and PAUL FRIENSEHNER, of Texarkana, in the county of Bowie and State of Texas, haveinvented certain new and useful Improvements in Gin-Saw-Sharpening Machines, of which the following is a specification.

Figure 1 is a perspective view of the stand and machine, showing how they are used together, dotted lines 3and 4 showing a gin-saw spindle and saws and how they are placed on the stand and how'the machine is applied to them to do its work. Fig. 2 is a sectional view of a box for a square shaft to revolve in, in place of a round shaft. Fig. 3 is a detailed side view of the adjustable top of frame. or stand with friction-roller box. Fig. 4 is a sec! tional front view through line 1 1 of Fig. 3 of the up-andrdown' adjusting mechanism of the shaft-arm of top of frame. Fig. 5 is a sectional end view through line 2 2 of Fig. 3 of the adjusting roller-box. Fig. 6 is a front View, on a larger scale, of the machine. Fig. 7 is a side view of Fig. 6,looking in direction of the arrow. Fig. 8 is a side viewfrom the opposite side.. Fig. 9 is a detail View of a side file-spring. Fig. 10 is a sectional view through line 12 12, Figs. 7 and 8, of side file-adjusting mechanism. Fig'. 11is a top view of the brushholders and their adjusting mechanism. Fig. 12 is aside view of the tallow-fountain. Fig. 13 is an end View of the center screw for spin dle-bar. Fig. 14 is a front view of square shaft-arm.

The object of our invention is to improve the construction of ginsaw Sharpeners, so that gin-saws may be sharpened with greater rapidity, certainty, exactness, and smoothness than by machines heretofore constructed. I

Our invention is described as follows:

The stand, Fig. 1, is made to hold any size and length of gin-saw spindle or arbor by the rollers 1), Figs. 3 and 5. The adjustable box I), with rollers b and spindle 3, can be brought to and from the shaft 6 and machine m by the adjusting-screw of, so that any size gin-saw, or one worn down to its smallest circle, can be sharpened, and the machine m being stationary on square shaft 6, Fig. 1, and shaft held to its place by screw 14, (right side arm,) it will be seen that the saws 4 can be sharpened and kept true to circle until worn-out.

The scale a Fig. 3, is to be a guide for adjusting roller-box b to an exact distance from shaft eon either end of stand, so that the saws 4, Fig. 1, will'be filed by machine or to an exact diameter from one end to the other. To keep spindle 3, Fig. 5, from moving to the left, which it will do when self-feeding file 7, Fig. 6, is at work, we shape rollers 11, Fig. 5, t0 fit in grooves usually turned in gin-saw spindles to keep them running true in their Babbitt bearings. \Vhere these grooves are not turned in,we have fiat-faced rollers b", Fig. 13, and keep spindle 3 in'its place by centeringscrew a screwing through frame a, which is screwed to top of stand a, Fig. 3, at a a The rollers b, b, and 1)", Figs. 3, 5, and 13, are made not only to fit grooves and any size spindle, but also to allow as easy a rotation to same as possible, in order to preserve the feed-tail of gumming-file 7, Fig. 6. I

Just here we would state that, the mechanism of machine or being stationary on the square shaft 6, Fig. 1 the action of said machine gives rotation to the saws 4 and spindle 3, carrying same toward machine at one tooth after another, as indicated by arrow on saw 4. This is accomplished by aid of the feed-tail 16 of self-feeding file'7, Fig. 6, and side files, 8, Fig. 7, rotating as shown by arrows. We do not in this application claim the mechanism of self-feeding file 7, this having already been patented by R. S. Mudford, July 27, 1880, No. 230,489. The stand is made to be adjustable in lengths to take up saw-spindles having forty, sixty, eighty, or one hundred or more saws by loosening set-screws f f, f 2 f Fig. 1, by which adjustment the rods f f can he slid out of their tubes f f f f until the required length is obtained.

The tubes f f f f are screwed into T- couplings c c 0 0 into which the two halves of iron-pipe legs a c and 0' 0 are screwed, holding the shaft-boxes d d. The legs a c c c are screwed into feet 0 c c of, that have holes for screwing to the floor, to which feet braces f 3 f f f and connectingrods c c are secured, giving strength and firmness to stand. Tight and loose pulleys d d can be belted to pulley of any shaft. On shaft dis arranged asliding pulley, d*, with key and set-screw (1 which pulley can he slid to where it may he wanted. Forlarge (one hundred and twenty five saw) gins we use the round shaft (1, Fig. 1; but for small country gins we make round or square shaft turned round on left side, where it is stationary and left loose for adjustment in the right-side box, d, Fig. 1,which is made as shown in sectional view, Fig. 2, where a round collar, 9, has a square central hole that square shaft (1 fits into, and which collar runs in a box, (1', kept in oil by oil-hole y", and kept in its place by flanges g g, that are screwed to box (1..

Square machine-shaft c, Fig. 1, is turned round on right end and tightened by set-screw 14, that works in a conical hole bored in shaft 0, Fig. 14. Said shaft is leftloose for adjustment on left end, as shown in sectional view, Fig. 4, where a round collar, a, has a square central hole for shaft 0, and a groove turned in collar a for screw a, to keep it from slipping out of shaft-arm a. By loosening screw 14, Fig. 1, the machine on can be moved about shaft 0 away from the saws 4, and by rotating saws 4 by the hand in the direction of arrow, to help the feeding-file 7 out of saw-teeth, the machine at is freed from saws. The machine set-screw h, Fig. 6 or 1, having also been loosened, the machine in can be slid to the next saw and moved circularly toward the saws 4 again until files 7 and S and brush 7 9 are in their place on saw-teeth. The machine setscrew h and shaftscrew 1t are then to be tightened, and the machine at is ready for work again. Belt 9 conveys power from sliding pulley d to machine-pulley Ve make machine m for steam or hand power. For handpower we fit a crank on file arbor u u or on gear t, Fig. 7 or S. The scale a, Fig. 14, is a guide for the up-and-down adjustment of shaftarm a to bring maehineshaft c to an equal height on either end.

The machine m, Fig. l, is shown in detail on a larger scale in Figs. 6, 7, S, and 10, where in Fig. 6 a n. are the saw-guides, keeping the saws from moving sidewise. The circular side files, S S, are to sharpen the .saws to a sharp-pointed taper, as shown at the ends of dotted lines 4 4; and 10 10 in Fig. 6, representing saws, t 4 being the center one that files 7 and S 8 are at work on, and 10 10 the one next to it on which the smoothing-brushes 3/ 3 are at work.

In position on the machine over the central saw, 4 4, is placed the tallow-fecd fountain a,

Fig. 12, of conical shape, with a small bottom that has a cut through center, where saw 4. extends through to the full depth of its teeth, or more. This cone-shaped box it contains the tallow, which is kept pressed by the hand are held by a spindle, 1). These springs bear upon files, keeping same in center, filing one side of saw as even as the other, and allow them to give when necessary instead of bolding them rigid. The files S are rotated by a gear, 12, keyed to spindle p by ascrew, p, which gear is offset from machine-frame m by a collar, 1). n

The files and spindle are held in a slide, 1, fitted to a straight groove, 1f, milled through the machine-framem, (also seen by dotted line 1:, Fig. 7.) The side file spindle p runs through the slide 1) and through slot at, Figs. 10 and 7. The adjusting-screw p is held in machine-frame m by a screw, p fitted loose into a groove of adjusting-screw p, as in Fig. 10. The side files, 8, Figs. 7 and 8, are thus made adjustable horizontally in machineframe in, room being milled out of frame, as shown by dotted lines rand q, where the frame is made in two halves. The smoothing-lnushes I 7 Figs. 6, 7-, and 8, move up and down vertically to the pitch of the saw-teeth. Brushes y i are screwed by threaded stems y 51 to holders Z, that have slots Z Z, Fig. 11, to allow of adjustment of brushes 7 1 until worn out.

The lower end of eccentric-rod 75', Fig. 6, is

receiving its rotation from gear 1', which also.

rotates gear 1) of side files. Gear 2" is a spur and a miter gear. The miter side i, Fig. 7 is rotated by mitergcar i", which is fastened to spur-gear i, that is fastened to filespindle a by screw 1) and rotated by gear i, which latter is fastened to a flange, j, and pulley j, that revolves on a spindle, j", and is kept in place by a collar, 7' and set-screw j. In Fig. 7, i is a projection of machine-frame; a, a screw to keep file-spindlc a in place; a", a nut, and a a washer.
